Furnace Thermostat Replacements

Your thermostat is more than just another piece of your furnace model. It's the nerve center for your home, where you can ensure consistent comfort for you and your family members. Whether low-voltage or high-voltage, they can break down and sometimes necessitate replacement.

The thermostat is the main control point of your furnace, which determines exactly how much heat should be delivered into the different rooms of your home, and when exactly the heating process should begin. However, what most people don't realize is that the thermostat is a very simple device, powered by just one heat-sensitive switch.

Browse through our full thermostat selection today to find the solution that best suits your needs, or reach out to us for more help. Remember, with Furnace Part Source, you can access same-day shipping on thousands of incredible parts from some of the world's top manufacturers.See also if certain items qualify for discounts or no order minimum.

Honeywell Furnace Thermostat

HVAC specialists like Honeywell for its commitment to high-quality air conditioning and furnace heating systems. The brand also works with specialists and contractors for proper installation. Working with others to create a smarter thermostat for your home is a high priority.

The Honeywell T6054A1005 Thermostat model has a range between -30 and 100 degrees Fahrenheit. It has OEM quality when professionals install it in your system.

Carrier Thermostats

Carrier was one of the creators of air conditioning, and maintains its status as a world leader. Innovation remains a constant priority during regular operations.

One good option is the Venstar VST1050 which replaces the Carrier TSTATCCPB501 thermostat model in older models. Carrier also provides a one-year warranty and installation manual to simplify the process for an HVAC technician.

Other Brands With Programmable Thermostats

Rockwell Heating as a company prioritizes sustainability. If a business reduces the amount of energy that escapes or has a moral hazard, then they create a better future. Rockwell thermostats carry the same mission.

A.O. Smith is another option when you want thermostats for gas furnaces and water-heating systems It’s why we can recommend the brand 9004769105 thermostat.

Signs Of A Heating And Cooling Thermostat Breaking Down

Like any other furnace component, a thermostat is subject to breakage and fault.Identifying when the device isn’t working will not only allow for efficient repairs but also reduce energy bills.

Check the display if a thermostat unit isn’t responding to you pressing buttons or attempting to adjust temperature. That could mean either the thermostat needs batteries, or you need to replace the display.

If the unit is not turning on, or it refuses to turn off, then it denotes a possible problem with the wiring. An HVAC specialist should check for connection issues to see if those need repairs.

Poor AC or furnace performance can be another sign. The temperature on a thermostat display may not match that which is in the room or area. If so, then the thermostat is not providing proper regulation.

Find The Ideal Type Of Thermostat From Furnace Part Source
